A simple epoxide modification strategy to construct amino-functional poly(2-oxazoline) mRNA delivery vectors.

ABSTRACT: Messenger RNA (mRNA) delivery vectors are pivotal in the realm of vaccines and gene therapy. While polymer-based delivery vectors have garnered growing interest owing to their tunable structures and favorable biocompatibility, achieving high delivery efficiency remains a critical challenge. Poly(2-oxazoline) (POx) emerges as a promising candidate in biomedicine, yet its exploration in mRNA delivery is nascent. Herein, we engineered poly[2-(5-aminopentyl)-2-oxazoline]-based (PAmOx) polymers as efficient mRNA delivery vectors through a straightforward one-step ring-opening reaction between the amino group on the PAmOx and the epoxide molecules. We conducted a systematic examination of how the degree of polymerization and the nature of grafted epoxide molecules influence mRNA delivery efficie
